Instrument Control Interface

1Introducing the Agilent 85225F Performance Modeling System

Instrument control interface is provided by a General Purpose Interface Bus (GPIB) or LAN/GPIB gateway. GPIB addresses for programmable system components are listed in Table 12.

Table 12 GPIB Addresses

Component	GPIB Address

Agilent 34401A digital multimeter	9

Agilent 35670A dynamic signal analyzer	10

Agilent 4156C precision semiconductor parameter analyzer	19*
Agilent 4284A precision LCR meter	24

Agilent E5810A LAN/GPIB gateway	21

Agilent E8364B PNA Series vector network analyzer	16

Agilent E5250A low leakage switch mainframe	22

Agilent E5260A 8-slot high speed parametric measurement mainframe	19

Agilent E5270B 8-slot precision parametric measurement mainframe	19

*The 4156C default GPIB address 17 is sometimes used by other devices with a GPIB address at 16 (for example, an external display (set to 17) to display the results generated by an instrument at address 16). Change the 4156C GPIB address to 19 using the procedure described in step 13 of “To switch on power to the system" on page 87 to ensure that IC-CAP can recognize the 4156C.
